Modern curb radius forces the pedestrian to walk twice as far in the path of a car traveling twice as fast. The image below shows just how far people have to walk, to enable motorists to efficiently swing around the corner with more speed. If the corner is sharper this would mean the

This video from Streetfilms is a lighthearted look at how piles of snow in New York provide useful street details that change the behaviour of drivers and make the environment safer for pedestrians. It is a good illustration of the point made above in the illustrations, that if kerbs have sharper radii, cars need to slow down to take the corner to a speed more suitable for residential areas.
This zebra crossing, the "Ergo Crossing", designed by Jae Min Lin for the Seoul Design Fair is said to be "ergonomic" because it follows the line people desire to walk in when they cross a road. Pedestrian crossings normally demand that people either make an abrubt 90º turn to both enter the crossing and also when they reach the other side. Which would be a bizzarre way to walk across the road, in fact people habitually cut the corner, but it's possible this can lead to conflict with the space designated for cars. This ingenious crossing is shaped to make allowance for how people really move in the city. It's just more honest.
Jaywalking - a punishable crime in the USA is where pedestrians cross the road anywhere other than exactly on the designated crossing. This law supposes that there are enough crossings and that they are approprately positioned http://gajitz.com/innovative-crosswalk-idea-makes-street-safe-for-jaywalkers/
